Let me start off by saying that if you plan to use this under mascara, then you def need to be ready to apply the mascara when the serum is moderately dry! I made the mistake this morning of letting mine dry all of the way, my mascara clumped almost nightmarishly!!

Stumbled upon this while @ Target or Walmart and paid around $7 for the tube. I used to use the L'Oreal serum with the rubbery applicator but haven't been able to find it for some time. I bought this and have only been using at night but have noticed a big improvement with my eyebrows. I have a hereditary disease, Hashimoto, that affects my thyroid function and has caused my hair to become finer and my eyebrows and lashes to almost disappear. I thought I would give this a try and didn't pin much hope to it but have been amazed at the results. My eyebrows are starting to grow back in and thicken nicely and I have noticed my length and volume in my lashes. Since I have only been using at night, I have decided to start doubling my usage and apply in the morning as well, I hope to see better results in a faster time period.

The only complaint I would have, and it is minor, is that this makes my lashes and brows "crunchy" after it dries. For morning use, I plan to apply after I wash my face and allow to dry before running a spoolie over my brows and lash comb through my lashes prior to applying my make-up, I hope it works and the serum maintains it's effectiveness.

This product does work! It may not be as fast acting as some of those more expensive lash serums, but it does work. I started off using it twice a day, in the morning after I washed my face and at night after I washed my face. I noticed a difference about two weeks in (now I only use it at night). I even used it on my eyebrows where they were a little thin, and after years of struggling to get the shape I want it's finally happening. *A WORD OF ADVICE: after it is absorbed into the lash it will peel off, so don't coat the entire lash. Use the little brush to line the eye like you would with eyeliner. The new growth will be "fragile" and when the serum peels off it could pull lashes out with it which defeats the purpose. If you have put mascara on use a gentle makeup remover to wash it off so you're not scrubbing. Other than that, it's a great product for a very reasonable price.

1st of all, I only review products that are worth my 2 cents...This is one of them. I was a skeptic...I admit it...but I actually love it. After I murdered my natural eyelashes by applying fake eyelashes which later refused to come off,(and only did after pulling 50% of my lashes out n breaking the rest in half) I was looking for a product (ehemm latisse) to rescue them. Fortunately I did my investigative work online n came across this product. I'm fascinated. 2 weeks later my lashes look slightly longer and fuller. I see new eyelash growth. However, I've noticed that if I skip a day n don't apply it my eyelashes look blah again (but not as bad as they were). I conclude they leave residue on your eyelashes which make them look fuller but who knows. I love it. Would definitely recommend giving it a shot, I will upload before and after pics after my 30 day trial. I'll keep you guys posted.

Honestly, I bought this product with different intentions than the results I began to notice. I bought the serum as a substitute for my mac prep and prime lash serum, which is only a months worth for each tube. I did a little research and i came across this beauty! First off, as far as my eyelashes, it took me a quite a long time until i saw a difference, and now , 3 months later i do see a reasonable difference, my lashes aren't crazy long or appear to be falsies by any means, but i do have more volume and length. secondly, i also read you could use the serum on your eysbrows too, my brows have always been sparse ,thin, and not the shape i wanted them. after about a month of applying the serum to my brows day and night I saw AMAZING progress! my brows are fuller, less sparse, and are becoming a nice shape, all thanks to this baby!(:, sooooooo happy with the results, whereas before i had an entire ,in depth brow routine, i now only need a light pencil to do the job!(:

this serum works. been using it for 3 months nightly. it made my lashes grow and have a bit more bounce. but you cannot skip this nightly treatment. I made the mistake of not using it for 2 weeks due to my overconfidence of the results: bam! my eyelashes went back to normal. not good! moral of the story? you have to treat this product as if you were either: taking your vitamins, plucking your eyebrows, brushing your teeth. you cannot skip this regime. otherwise you'll think the product doesn't work. one more thing. ..a fellow reviewer was right- do not apply this and then apply your mascara. ..it will cause for your eyelashes to clump. also on the morning after you will notice your eyelashes have a somewhat transparent string..kinda like dried rubber cement...this is normal. love the product and will continue to use it until I can get a hold of the ingredients to make my own.

Update

tried a homemade lash serum, well epic fail. but shea butter is a great lash accelerator. so try pure unbleached shea butter if the serum by rimmel is out of stock.

I give it a 3 ONLY because I've never tried another lash serum. I got it half off, so I thought I'd give it a go for only a few dollars. After one week, my lashes were longer! I am a stay at home mom, so I don't wear makeup when I'm home, so I basically had this stuff on 24/7. After a couple weeks, when I put on mascara I was amazed! My lashes were so long! An I have SUPER short, thin lashes. This is so affordable, and works! It is proven, because it contains CASTOR OIL. I look forward to buying the matching mascara with the serum in it as well!

Wanting something more conditioning during the day, I decided to try this in place of my Anastasia clear brow gel. It's fabulous!! It holds beautifully (I would say as strong as my beloved Anastasia gel!) and I get to apply growth and conditioning product during the day now! I use a disposable mascara wand, insert it into the product tube, and apply as I would any clear brow gel to help set my brows and hold my Anastasia powder. I haven't found it to be too goopy, as long as I keep a light to moderate hand. I'm not a fan of the built in brow applicator for daytime use, though it is fine for bedtime when brows don't need to look perfect. ;) I use Rapid Lash on lash lines and brows in the evening (LOVE this stuff), so don't typically use this then, but I would be in heaven if Rapid Lash would package their product like this... Great job, Rimmel! Plenty of product, clear packaging to see how much product is left, and I appreciate the novelty of the wand, even if it could be improved slightly.

I also use this serum on my lash line during the day, after face makeup, but before eyeliner (I use a pencil some days and cream/gel liner other days...application still looks flawless either way). I use a very light hand so I don't get that rubbery line when dried. I also make sure to wipe any extra off my lashes, or they won't hold a curl. I use the accompanying Rimmel Accelerator Mascara as my final eye step (which I don't love, but that's for a different review). Can't tell that I'm wearing this serum at all...as long as it's a light application.

I'm really loving the conditioning aspect of this serum. I love my Rapid Lash and have been using it for a few months now with TONS of new growth and length, but I noticed a big difference in the condition of my lashes and brows when I added this Rimmel serum to the mix. Lash and brow hairs were glossy and shiny, even when I was fresh out of the shower with no product on. I've used straight castor oil (which is a main ingredient in this), but it never did what this is doing for me. Love it!

I started using this on December 28, 2013 and i'm currently still using it and I can say that it does work. I initially got this for my eyelashes and I use it both on my eyelashes and eyebrows. I saw a difference in my lashes in the first week. after like a couple of weeks of using it I could tell that it was working because when I would put my mascara on in the morning the lashes were all different sizes.. which was frustrating for like a week because the mascara didnt look good on my growing lashes. for like the first 3 weeks I had a couple of lashes falling out when id take off my make up. but after 5 weeks of using it I no longer have any lashes falling out. my lashes are much much longer than they were before, they're way stronger. I also think they're thicker cause it doesn't require a lot of mascara to get the full look like before, I will continue to use this until im out.

I bought this based on reviews that people said they saw growth in their eyelashes and eyebrows in 1-2 weeks. Also because it was $8 at shoppers drug market which is pretty cheap compared to other expensive lash growth treatments. I used this until the bottle ran out which was about 1 month or so. I don't notice any growth in my eyebrows or eyelashes. I use the serum day and night. The only benefit I did receive from this was that my eyelashes fell out a lot less. It was worth a shot but won't buy this again.
